Skyworks offers a broad range of ceramic materials that are not
characterized for resonator applications, but for bulk,
miscellaneous shapes, or substrates. Typical applications include
patch antenna substrates, matching structures for circulators and
isolators, and miscellaneous support structures. Because such
applications are non-resonant, temperature coefficient of
resonant frequency does not apply, and we therefore list the temperature dependent coefficients of dielectric constant and linear expansion.
The Magnesium Aluminum Titanate (SMAT) and Magnesium
Calcium Titanate (MCT) series are notably easier to machine than
most microwave ceramics, and may be more suitable for
applications requiring precision machining.
D-4, or Corderite, is a very hard ceramic noted for its low
temperature coefficient of expansion which approaches the metal
alloy Invar. It is not suitable for substrates. It is occasionally used
for dielectric resonator supports due to its low dielectric constant
and/or low thermal expansion rate.
